Is it possible to make outbound call from sip trunk using api?

We use the following api to make an outbound call. Can we use a sip address in the From parameter to use SIP trunk.

    $call = $client->calls->create(
    "+1XXXXXXXXXX", "+1XXXXXXXXXX",
    array("url" => "http://demo.twilio.com/docs/voice.xml")
    );

    You cannot provide a SIP address as a From parameter when making calls. The documentation describes the required parameters for a call as:

    Parameter   Description

From        The phone number or client identifier to use as the caller id.
            If using a phone number, it must be a Twilio number or a Verified
            outgoing caller id for your account.

To          The phone number, SIP address or client identifier to call.

    So, you can only use a phone number or a client identifier. The To parameter can be a SIP address, so you can make calls from the API to a SIP address, just not from one.

    If you are using SIP trunking you need to initiate calls via SIP.
